Mercedes V-Class W447 (2014-Today) Diesel Particulate Filter DPF

The Diesel Particulate Filter (DPF) on the Mercedes V-Class W447 (including models like V 200, V 220 CDI/d, V 250, V 300, EQV) is a crucial exhaust system component that captures fine particulate matter from diesel engine emissions. It helps the vehicle comply with Euro 4, 5 or 6 emission standards. The DPFs are typically made from silicon carbide or cordierite, with lengths around 960 mm or 1260 mm, and weigh between 6 and 8.5 kg.

A defective or clogged DPF can cause:

• Increased fuel consumption
• Loss of engine power
• Check Engine warning light activation

Addressing these symptoms early can prevent further engine damage.

DPF cleaning can be done by:

• Passive cleaning: Driving at 60-80 km/h for 25-30 minutes to reach regeneration temperature and burn off particulates. Maximum ash limit is about 60 g.
• Active cleaning: Using diagnostic tools (like VCDS) to force DPF regeneration.
• Chemical cleaning products: Using additives such as CARTECHNIC aerosol cleaners to assist soot removal.

Regular cleaning extends the DPF lifespan and maintains vehicle performance.

DPF replacement is generally recommended within the interval of 135,000 to 175,000 km to prevent malfunctions. Replacement filters are compatible with diesel OM 654 engines (e.g., V 220 CDI/d, V 250 CDI/d) and meet Euro 5/6 standards with OBD compliance.

• OEM part references include A4474900083 and 4474903700.
• Ensure installation by authorized centers following manufacturer instructions for warranty coverage.

Replacing the DPF proactively helps maintain emission system performance and fuel economy.

Typical specifications for compatible DPFs include:

• Materials: Silicon carbide or cordierite
• Weight: 6 to 8.5 kg depending on model
• Lengths: 400 mm, 960 mm, 970 mm, or 1260 mm variants
• Emission standards: Euro 4, 5, and 6 compliant
• Features: Equipped with OBD sensors and sometimes mounting kits included

Using correct DPF specifications ensures compatibility and optimal system function.
